MED INSTITUTE PROPOSES THE DEVELOPMENT AND TESTING OF AN INNOVATIVE PORTABLE CONSTANT-TILT DEFIBRILLATOR WITH AN LCD-ECG MONITOR. THE DESIGN APPROACH IS BASED UPON YEARS OF DEFIBRILLATION RESEARCH THAT HAS RESULTED IN DEFIBRILLATOR DESIGN EQUATIONS FOR OPTIMAL USE OF ENERGY. CONSTANT-TILT CONTROL PROVIDES COMPENSATION FOR HIGH THORACIC IMPEDANCE BYAUTOMATICALLY INCREASING THE DURATION OF THE TRUNCATED EXPONENTIAL WAVEFORM. THE EFFICACY OF THE PROTOTYPE WILL BETESTED ON PIGS BY THE RESEARCH TEAM AT PURDUE. ALSO DURING PHASE I, A MARKETING STRATEGY WILL BE DEVELOPED.
